The line comes from JoJo's Bizarre Adventure: Golden Wind, the 2018 anime adaptation of Hirohiko Araki's fifth part. It is shouted by Diavolo, the secretive boss of the Passione gang, during his final confrontation with Giorno Giovanna in Rome. Clips of the shout spread through anime meme edits, JoJo compilations, and TikTok audios, where it now sits alongside staples like Za Warudo - Anime's Time Stop and To be Continued (jojo). Its staying power comes from that theatrical Araki villain energy fans love quoting.
